Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier for designer-led sites. S-tier if animations matter.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.
